[U-Boot] [PATCH v5 24/25] riscv: bootm: Change to use boot_hart from global data

[Bin Meng]

Avoid reading mhartid CSR directly, instead use the one we saved
in the global data structure before.

With this patch, BBL no longer needs to be hacked to provide the
mhartid CSR emulation for S-mode U-Boot.
